Maybe this is an elementary question, but I'm unable to find the appropriate reference for it. The Stokes theorem tells us that, for a n+1n+1-dimensional manifold M with boundary partialM and any differentiable n-form omega on M, we have intpartialMomega=intMdomega.
But Stokes theorem is also true, say, for a cone M=(x,y,z)inmathbbR3vertx2+y2=z2,0leqzleq1, or a square in the plane, M=(x,y)inmathbbR2vert0leqx,yleq1 which are not manifolds. So my questions are:
- Are these cone and square examples of what I think are called "manifold with corners"?
- If this is so, where can I find a reference for a version of Stokes' theorem for manifolds with corners?
- If "manifold with corners" is not, which is the appropriate setting (and a reference) for a Stokes' theorem that includes those examples?
Any hints will be appreciated.
EDIT: Since thanking individually everyone would be too long, let me edit my question to acknowledge all of your answers. Thank you very much: I've found what I was looking for and more.
